Have you tried putting it in as an Alt code? On a Windows machine, hold down Alt and press 0174 on your 10-key, then let go of ALT and that should insert it into the course. If you are on a Mac, press Option + r.

Well "works for" isn't quite the way I'd put it has you have to "character map" , then find the right font, then scroll and scroll and scroll and hope that the right glyph is there just waiting for you to come find it.

What would work for me is hitting this pretty <HTML> button, going &#8212; , and then hitting that button and going back to WYSIWYG mode. But, I can dream.
